According to the file nanu1997.mes obtained from the IGS CBIS, PRN23 was
unusable on day 035 for maintenance/repositioning. Data from this satellite
did not meet our initial convergence criteria on this nor the following day
(036) and have been excluded from these days' analyses.
Due to potential problems, data from stations mentioned below were not
considered for use in the global solution for the day indicated. (For
geographical reasons, they may not have been used in any case.)
WARNING: Data from PRN23 excluded days 034 and 035 due to a manuever.
WARNING: Data from AUCK, CHAT, HFLK, WTZR excluded day 033.
WARNING: Data from AUCK, CHAT, HFLK, NYAL, WHI1, WTZR excluded day 034.
WARNING: Data from COSO, WEST, WTZR excluded day 035.
WARNING: Data from CMBB excluded day 036.
WARNING: Data from COCO excluded day 039.
In the following table, UT1R-UTC are the integrated values based on estimated
LODR values in the adjacent column. See IGS Report No. 1498 (jpl07827.sum)
